Abstract

639,236. Feed mechanism for mechanical presses. TURNER BROS. (BIRMINGHAM), Ltd., and BLACKMORE, E. J. A. Dec. 3, 1947, No. 31879. [Class 87 (ii)] [Also in Groups XXII and XXIV j Mechanism for driving feed rolls for feeding strip stock into a press comprising a one-way clutch operated through a connecting-rod from a crank disc or the like on the main driving shaft of the press, is characterised by the provision of step-up gearing between the connecting- rod and the one-way clutch. Feed rolls 16 disposed on each side of a press 15 are driven from shafts 22 extending from the rolls one along each side of the machine to the rear, where they are driven from a shaft 26 through bevel gears 24, 25. Over-running of the rolls is prevented by means of brakes 47. At one end the shaft 26 has an extension 28 on which is mounted a ratchet wheel 30 surrounded by a pawl drum 29. Rotatably mounted on the extension 28 adjacent the pawl drum and connected thereto is a sun gear 33 and a casing 34 which surrounds the sun gear and within which is mounted on a spindle 37, a half planet gear 35 meshing with the sun gear. The outer end of the spindle 37 is non- rotatably connected to the forked end of a rod 10 which is reciprocated by means of a crank disc 11 on the main crank shaft of the press. If it is desired to operate the rolls 16 without the step-up gearing 33, 35, the half gear is turned through 180 degrees so that it does not engage the gear 33, and the spindle 37 is moved longitudinally so that it projects into a hole 46 in the pawl drum which is thus directly operated from the connecting rod 10. The top roll of each pair is given an automatic lifting movement by means of a rod 17, rock shaft 18 and arm 19 operated by a cam on the main crankshaft.
